Fourth most populous Colorado county

Jefferson County (IPA: /ˈdʒɛfərsən ˈkaʊnti/) is the fourth most populous of the 64 counties of the State of Colorado of the United States. The United States Census Bureau estimates that the county population was 526,994 in 2006.[1] The county seat is Golden and the most populous city is Lakewood. Jefferson County is part of the Denver-Aurora Metropolitan Statistical Area and the Denver-Aurora-Boulder Combined Statistical Area. The center of population of the State of Colorado is located in Jefferson County.[2]

Located along the Front Range of the Rocky Mountains, Jefferson County is part of the Denver metropolitan area. The major expressway Interstate 70 traverses Jefferson County from east-to-west, passing just south of the county seat of Golden. Jefferson County is a quite long county from north to south, following the Front Range. The county is known as the Gateway to the Rocky Mountains.

A major employer in Jefferson County is the large Coors Brewing Company in Golden. Also, the state-supported Colorado School of Mines is located in Jefferson County, offering programs in mining and engineering.

Jefferson County is commonly nicknamed Jeffco. The name Jeffco is incorporated in the name of the Jeffco School District, the Jeffco Business Center Metropolitan District No. 1, and several businesses located in Jefferson County. Jeffco is also incorporated in the unofficial monikers of many Jefferson County agencies. The Rocky Mountain Metropolitan Airport operated by Jefferson County was previously known as the Jeffco Airport.

[edit] History

On 1855-08-25, the Kansas Territorial Legislature created Arapahoe County to govern the entire western portion of the Territory of Kansas. The county was named for the Arapaho Nation of Native Americans that lived in the region.

In July 1858, gold was discovered along the South Platte River in Arapahoe County (in present day Englewood). This discovery precipitated the Pike's Peak Gold Rush. Many residents of the mining region felt disconnected from the remote territorial governments of Kansas and Nebraska, so they voted to form their own Territory of Jefferson on 1859-10-24. The following month, the Jefferson Territorial Legislature organized 12 counties for the new territory, including Jefferson County. Jefferson County was named for the namesake of the Jefferson Territory, Thomas Jefferson, the principal author of the United States Declaration of Independence and the third President of the United States. Golden City served as the county seat of Jefferson County. Robert Williamson Steele, Governor of the Provisional Government of the Territory of Jefferson from 1859 to 1861, built his home in the county at Mount Vernon and later at Apex.

The Jefferson Territory never received federal sanction, but on 1861-02-28, U.S. President James Buchanan signed an act organizing the Territory of Colorado.[3] On 1861-11-01, the Colorado General Assembly organized the 17 original counties of Colorado including a new Jefferson County. In 1908, the southern tip of Jefferson County was transferred to Park County, reducing Jefferson County to its present length of 54 miles (87 kilometers). Several annexations by the City and County of Denver and the 2001 consolidation of the City and County of Broomfield removed eastern portions of the county.
